At 90 degrees the yaw is extremely unstable (tested with HIL), it
overshoots and only very slowly converges to the correct value.
This behavior is also noticable with lower angles, but not so extreme.
It definitely needs to be looked into further, but for now this makes it
safer.

This enables mavlink user input not only in the range of [-180..180]
degrees but also [0..360] degrees.

This commit changes old trone driver into a generic
TeraRanger driver that supports both TeraRanger One
and TeraRanger Evo.

As a part of the change a new parameter was created
SENS_EN_TRANGER that allows to specify the following
modes of operation:

0 - sensors disabled
1 - autodetect sensors
2 - use TeraRanger One rangefinder
3 - use TeraRanger Evo rangefinder

The calculation of the ARR on the LED PWM timer did not subtract 1
from the timer period calculation to get the ARR value.

Now the start up script starts a GPS simulator as well as the ekf in order
to estimate position and orientation
